Answer:

85 minutes.

Step-by-step explanation:

T = Tuesday

M = Monday

T = M - 15,   70 = M - 15,   M = 85 minutes.

Since she worked out 15 minutes less than monday on tuesday, you add 15 to 70, since thats what she did on tuesday.

Answer:

\sf \dfrac{203}{4108}

As a decimal = 0.05 (nearest hundredth)

Step-by-step explanation:

\sf Probability \ of \ an \ event \ occurring = \dfrac{Number \ of \ ways \ it \ can \ occur}{Total \ number \ of \ possible \ outcomes}

First pick:

\sf \implies P(pink)=\dfrac{30}{80}

As the case is NOT replaced, second pick:

\sf \implies P(pink)=\dfrac{30-1}{80-1}=\dfrac{29}{79}

As the case is NOT replaced, third pick:

\sf \implies P(pink)=\dfrac{29-1}{79-1}=\dfrac{28}{78}

Therefore,

\sf \implies P(pink \ and \ pink \ and \ pink)=\dfrac{30}{80} \times \dfrac{29}{79} \times \dfrac{28}{78}=\dfrac{203}{4108}

Answer as a decimal = 0.05 (nearest hundredth)

What is the solution of the system of equations? y = –3x + 8 y = –5x – 2
jekas [21]
y=-3x+8 \\ y=-5x-2 \\  \\ -3x+8=-5x-2 \\ -3x+5x=-2-8 \\ 2x=-10 \\ x=- \frac{10}{2}  \\ x=-5 \\ y=-3(-5)+8=15+8=23  \\ \\ \boxed{-5,23}

Find the volume of a right circular cone that has a height of 10.7 in and a base with a diameter of 8.1 in. Round your answer to
scoundrel [369]

Answer:

V = \pi r^2 h

And for this case the value for the height is h = 10.7 in the diameter is provided D = 2r = 8.1 in so then the radius is given by:

r = \frac{D}{2}=\frac{8.1 in}{2}= 4.05 in

Then we can find the volume with the first formula and replacing we got:

V = \pi (4.05in)^2 (10.7 in)= 551.4 in ^3

The final answer for this case would be 551.4 cubic inches

Step-by-step explanation:

The volume for a right circular cone is given by this formula:

V = \pi r^2 h

And for this case the value for the height is h = 10.7 in the diameter is provided D = 2r = 8.1 in so then the radius is given by:
